Pressing device for applying a compressive force to products of a product display device, shelf unit and product display device

Abstract

A pressing device for applying a compressive force to products of a product display device includes a pressing part for transmitting the compressive force. The pressing device has a mass body with a predefined mass. The pressing device includes a support part carrying the mass body, which is movably connected to an inclined surface carrying the products. An assembly comprises a shelf element having a set-down surface for products, and a pressing device for applying a compressive force against the products.

The invention claimed is: 
     
       1. A pressing device ( 1 ;  1 ′;  1 ″;  1 ′″) for applying a compressive force (F) against products ( 400 ) of a product display device ( 200 ), comprising:
 a pressing surface ( 2 ) for transmitting the compressive force (F) to the products, the pressing surface ( 2 ) being part of 
 a mass body (M 1 ; M 2 ) having a predefined mass for applying a defined weight force by which the compressive force (F) is effected; and 
 a support part ( 6 ;  6 ′;  6 ″;  6 ′″) carrying the mass body (M 1 ; M 2 ), which is configured to be movably connected to an inclined surface ( 40 ) carrying the products ( 400 ), in order to allow a movement of the pressing device ( 1 ;  1 ′;  1 ″;  1 ′″) along the inclined surface ( 40 ), 
 wherein the mass body (M 1 ; M 2 ) is fastened to the support part ( 6 ;  6 ′;  6 ″;  6 ′″), 
 wherein the support part ( 6 ;  6 ′;  6 ″;  6 ′″) includes
 two parallel guide surfaces ( 14 ,  15 ) spaced apart from one another and configured to cooperate with counter-guide surfaces of a shelf element ( 50 ) to form a linear guide, 
 two securing surfaces ( 16 ,  17 ) extending towards one another from lower ends of the parallel guide surfaces ( 14 ,  15 ) perpendicular to the guide surfaces ( 14 ,  15 ) and below the shelf element ( 50 ), the two securing surfaces ( 16 ,  17 ) being configured to prevent the pressing device ( 1 ;  1 ′;  1 ″;  1 ′″) from being lifted off the shelf element ( 50 ), and 
 a sliding surface ( 27 ) extending perpendicular to the guide surfaces ( 14 ,  15 ), the sliding surface ( 27 ) being supported on the inclined surface ( 40 ) of the shelf element ( 50 ), and 
 
 wherein the two parallel guide surfaces ( 14 ,  15 ), the two securing surfaces ( 16 ,  17 ), and the sliding surface form two U-shaped portions of the support part ( 6 ;  6 ′;  6 ″;  6 ′″) that face each other and receive the shelf element ( 50 ) therebetween. 
 
     
     
       2. The pressing device according to  claim 1 ,
 wherein the mass body (M 1 ) comprises a base body ( 3 ) with a cavity ( 4 ), in which a predetermined quantity of a pourable and/or flowable material ( 5 ) is filled, in order to generate the defined weight force. 
 
     
     
       3. The pressing device according to  claim 2 ,
 wherein the cavity ( 4 ) comprises a seal ( 9 ) in order to hold the pourable and/or flowable material ( 5 ) in the cavity ( 4 ). 
 
     
     
       4. The pressing device according to  claim 2 ,
 wherein the base body ( 3 ) is a dimensionally stable container filled with solidified concrete material. 
 
     
     
       5. The pressing device according to  claim 1 ,
 wherein the support part ( 6 ;  6 ′;  6 ″;  6 ′″) comprises a carriage ( 11 ) to form a linear guide with a profile rail ( 52 ) having the inclined surface ( 40 ). 
 
     
     
       6. The pressing device according to  claim 2 ,
 wherein the support part ( 6 ;  6 ′;  6 ″;  6 ′″) has a contact surface ( 24 ) and the mass body (M 1 ; M 2 ) and/or the base body ( 3 ;  3 ′″) has a counter-contact surface ( 28 ), which are formed as an adhesive surface and the support part ( 6 ;  6 ′;  6 ″;  6 ′″) and the mass body (M 1 ; M 2 ) and/or the base body ( 3 ;  3 ′″) are fastened to one another thereover by means of an adhesive. 
 
     
     
       7. The pressing device according to  claim 6 ,
 wherein the adhesive is a single component adhesive. 
 
     
     
       8. The pressing device according to  claim 1 ,
 wherein the support part ( 6 ;  6 ′;  6 ″;  6 ′″) is an integrally molded plastic part, which consists of a plastic material. 
 
     
     
       9. The pressing device according to  claim 1 ,
 wherein the pressing surface ( 2 ) is formed by a wall section ( 10 ) of the mass body (M 1 ; M 2 ). 
 
     
     
       10. The pressing device according to  claim 1 ,
